Identify the nuclear reaction that differs from the restA. Positron em

1.	Identify the nuclear reaction that differs from the restA. Positron emissionB. K-captureC. `beta-`decayD. `gamma-`decay
Answer» Correct Answer - D `beta-`emission occurs in those radioactive elements in which n/p ratio is higher than required for stability. In `beta`-emission n/p ratio decrease, where as `alpha` emission , positron emission and K-capture occus in those elements in which n/p ratio is lower than required for stability. Alpha emission is usually observed in nautral radioactive isotope while emission of positron or K-capture is observed in artificial radioactive isotope. There is no change in n/p ratio due of `gamma`-emission
